Rules are rules. A race bike needs to conform in order to qualify for UCI-sanctioned races. But designing a frame that's significantly more slippery through the air, without breaking the rules? That's completely legit. The Litening® AERO lightweight carbon chassis – built with our premium C:68X® material – was designed with extensive use of Computer Fluid Dynamics and real-world wind tunnel testing. The result is a significant 30% reduction in drag, in a fully UCI-compliant frame that elegantly integrates fork, stem, handlebar and seatpost. It's also extremely comfortable and has clearance for tyres up to 28mm. But most important of all, it's very, very fast.
